FAQ

Why install kfc-procedure but import kfc_procedure?

PyPI package names can contain hyphens, but Python imports cannot. Use pip install kfc-procedure and import kfc_procedure.

Which divergence should I start with?

Start with euclidean, because it supports real-valued data without special domain constraints.

Why do gkl, is, or logistic fail?

Their domains are restricted. gkl and is require positive data. logistic requires values in (0, 1).

How many clusters should I use?

Start with 2 or 3. Too many clusters can make local models unstable.

Can I use sklearn models?

Yes. The package auto-registers many sklearn estimators using snake_case names such as linear_regression, decision_tree_classifier, and random_forest_regressor.

What is COBRA?

COBRA is an ensemble aggregation method that compares samples in prediction space and aggregates nearby targets using kernel weights.
